A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are mouldable.               Plastics are typically organic polymers of high molecular mass, but they often contain other substances. It is a white, waxy polymer constituted of only carbon and hydrogen.The drastic rise in the use of non-biodegradable plastic materials during the past decades has not been accompanied by corresponding development procedure for the safe disposal or d...

A spherical harmonic model of the lunar gravity field complete to degree and order 70 has been developed from S band Doppler tracking data from the Clementine mission, as well as historical tracking data from Lunar Orbiters 1-5 and the Apollo 15 and 16 subsatellites. The model combines 361,000 Doppler observations from Clementine with 347,000 historical observations. The historical data consist of mostly 60-s Doppler with a noise of 0.25 to several mm/s...

[texts]The Effect of Vacuum Carbonization of Waste Maize Stalk on the Thermal Resistance of Polyester/Maize Stalk Particulate Composites
The effect of vacuum carbonization of waste maize stalk on the thermal resistance of polyester/maize stalk particulate composites has been investigated. Maize stalk was carbonized at a temperature of 1200oC to convert the biomass into biocarbon; then the carbonized maize stalk was used to reinforce polyester while the uncarbonized ones served as the control. The carbonized maize stalk particulates (CMSp) were added with different volume fractions into a polyester matrix at an interval of 2, 4, 6...

[texts]Knowledge Representation Standards and Interchange Formats for Causal Graphs - Throop, David R.
In many domains, automated reasoning tools must represent graphs of causally linked events. These include fault-tree analysis, probabilistic risk assessment (PRA), planning, procedures, medical reasoning about disease progression, and functional architectures. Each of these fields has its own requirements for the representation of causation, events, actors and conditions. The representations include ontologies of function and cause, data dictionaries for causal dependency, failure and hazard, an...

[texts]New Air-Launched Small Missile (ALSM) Flight Testbed for Hypersonic Systems - Bui, Trong T.
A new testbed for hypersonic flight research is proposed. Known as the Phoenix air-launched small missile (ALSM) flight testbed, it was conceived to help address the lack of quick-turnaround and cost-effective hypersonic flight research capabilities. The Phoenix ALSM testbed results from utilization of two unique and very capable flight assets: the United States Navy Phoenix AIM-54 long-range, guided air-to-air missile and the NASA Dryden F-15B testbed airplane...

[texts]Improvement of Raman lidar algorithm for quantifying aerosol extinction - Russo, Felicita
Aerosols are particles of different composition and origin and influence the formation of clouds which are important in atmospheric radiative balance. At the present there is high uncertainty on the effect of aerosols on climate and this is mainly due to the fact that aerosol presence in the atmosphere can be highly variable in space and time. Monitoring of the aerosols in the atmosphere is necessary to better understanding many of these uncertainties...

[texts]Use of Partially Purified Banana Peel Polyphenol Oxidase in the Degradation of Various Phenolic Compounds and Textile Dye Blue 2RNL - Jadhav, U., Salve, S., Dhawale, R., Padul, M., Dawkar, V., Chougale, A., Waghmode, T., Salve, A., Patil, M.
Polyphenol oxidase (PPO) enzyme was isolated from banana peel. Enzyme was partially purified by ammonium sulphate precipitation (70%). The partially purified PPO showed optimum temperature 35 oC and pH 7.0. This PPO enzyme preparation was employed for the degradation of four different phenolic compounds and textile dye Blue 2RNL. PPO degraded 1 g/L gallic acid (100%) in 24 h. PPO also decolorized 40 mg/L Blue 2RNL dye (89%) in 24 h...

The molecular weight of PET waste powder was found to be 8851. The minimum amount of sodium hydroxide and pyridine required for maximum recovery was found to be 7g. and 3.0cm 3 respectively. Further, it was observed that minimum particle size of 100 µm of PET waste powder gave maximum conversion to TPA...
